Permafrost on the tibet plateau

WebPermafrost regions contain large organic carbon pools. A deep core was taken in permafrost from the northern Qinghai-Tibet Plateau (QTP) and exposed to increases in temperature below and above 0°C. The production of CO2 was related to the soil organic carbon (SOC) contents and stable carbon isotopes. WebAbstract: Landslides are one of the major geohazards in the Qinghai-Tibet Plateau, and have recently increased in both frequency and size. SAR interferometry (InSAR) has been widely applied in landslide research, but studies on monitoring small-scale landslides are rare.
